Ive tried those granules and They work ok in veg. but there is simply too much nitrogen and too little phosperous, If you plan on using it I would use about 1/2 to 2/3 of what they recommend on the package and use a high P fertilizer like the shultz on the side. And I would flush the medium for at least 1 week before harvest because this will help get rid of the waste/nutes in the soil and the bud will taste far better. But I highly recommend getting botanicares new Organicare Granules (Grow and Bloom) They cost about 6 bucks for a 2 lb bag and they are much better than the Garden club. Plus there would be no need for the shultz with organicare.
